Fistula is usually located in the patient's arm or leg. During hemodialysis treatment, in order to ensure smooth and stable blood flow, the limb where the fistula is located needs to be fixed in an appropriate position. Therefore, a hemodialysis fistula limb fixation device is needed.
[0003] After searching, Chinese patent announcement number: CN204709120U discloses a fistula puncture limb fixation frame, which belongs to the field of medical device technology, and solves the problem that the existing fistula puncture limb fixation frame is not stable in hand fixation and has potential safety hazards.
